The only way it could hurt is if you are using cuffs or a leather restraint and they are too tight or rubbing you wrong. Usually, though, you won't get hurt using one of these
It's never hurt me before. The only way I could see it hurting would be if the straps are too tight or you're in an uncomfortable position to start with.
